Appncaaon mea March 12, 192e. serial No. 94,348.

This invention relates to brushes and particularly to devices of this Vcharacter adapted to be secured to a stationary member while the articles to be operated upon are moved beneath the projecting. bristles thereof, the object of the invention beingv the production ofa brushin which the bristles may be renewed as desired.

' This object is attained bythe mechanism illustrated in the.Y accompanying drawings.

For the purpose of illust-ratingtheinvention, one preferred form thereof is illustrated in the drawings,- Ythis form having been found to give satisfactory and reliable result-s, although it is tobeV understood Ithat the various instrumentalities of which the invention consists can lbe variously arranged and organized, and the invention is not limited vto the precisearrangement and 0rganiZat-ion of these instrumentalities as here-` in shown and described except as required .by the scope of the appended claims.

Of the drawings: Figure 1' represents a horizontal section of a brush embodying the principles of the present'invention, the cutting plane being on line 1, 1, on Fig. 2. v

Figure 2 represents a longitudinal verti.- lcal sect-ion of Vsame V.on 'line-2,12 on Fig. 1. Figu-re represents a transverse vertical section of same on line 3, 3,7on Fig. 1.

Figure -4 `represents a front elevation .of one ofthe bristle-supporting units. Figure-5 represents avertical section of 3f saidunit on line 5, 5 on Figure 4 and drawn to an enlarged scale.

Figure `6 represents a verticalA section of said unit'on line, 6 Von Fig. 4, and also drawn to an enlarged scale.

U10 Y Figure 7 represents an elevation of one of the plates forming the bristle-supporting vunitand showing the inner face thereof.

`l*`igure 8 represents an elevation .of the other plate for-ming the bristle-,supporting unit and showingthe inner face thereof,

and f IFigure9 represents a plan of two bristle- .supporting .units with theircorrugations staggered and showing one ofthe grooved clamping plat-es coacting with the outer unit. Similar characters indicate. like parts throughout 2rthe .several figures of the drawmgs.

In the drawings, 10, 10 are the side memyends of which are flat and in Contact, as

toea`ch VLil-shaped connector 12."

bers of a frame having kpivoted, at 11, to the ends thereof, the U-shaped connecting members 12.

AEach side member consists of a plate 10 having disposed on the inner face .thereof two channel bars 13 and 14, secured to the 60 plate 10 by rivets 15.

rFhese channel bars 13 and 14 form oppositely disposed grooves in which are disposed a plurality of bristle-supporting units 16V having projections 17 at the opposite ends thereof extending into said grooves,

Each bristle-supporting unit 16 is composed oftwo plates 18 and 19, the upper shown in Figs. 5 and 6, while the lower poreA 70 tions thereof have corrugations 20 formed therein. f

These corrugations are .oppositely disposed in pairs forming sockets 21 in which a plurality of bristles 22 are positioned.

rEhe bristles 22 extend to the inner end of each socket 21 and by this end are prevented from moving inwardly.

Each corrugation has an indentation or crease 23 formed therein which extends inwardly into lthe socket 21 and impinges upon the bristles 22, thereby preventing any outwardmovement of said bristles.

The plate 19 has a plurality of nctches 24 in the opposite edges thereof, and the plate 18 has at its opposite edges projecting ,clips 25 which are adapted to' be bent over the plate 19 and positioned in the notches 24,

The plates 18 and 19 are also secured together by rivets 26 inthe opposite ends ofsaid plates.

.The bristle-supporting units 16 areadapted to be insertedin thef'grooves of thechan-A nel bar 14 in any desired number, land at the opposite ends of the series of units 16 are disposed clampingbars 27,` the inner faces of which are corrugated to fit the corruga-- tions in the bristle-*supporting units 16. p

When the series of units 1G are thus disposed within the grooves of the channel bars 100 14 and theclamping pla-tes 27 vare disposed at the opposite ends thereof, all o f the units are forced toward each rother .and clamped by means of anl adjusting screw 28, threaded Should the bristles of anyof the unitsbecomeunduly worn' the U-shaped connecting members 12 may be moved about their pivots 11 and the bristle-supporting units 16 removed and new ones inserted to replace those which have become unduly worn.

ln the grooves in the upper channel bar 18 are disposed cross bars 29 having bolts 30 extending upwardly therefrom through slots 31 in a stationary part 32 of a machine, the upper ends ot the bolt 30 having threaded thereto clamping nuts 33.

These bars 2E) may be adjusted endwise ot the channel bars 13 "and then clam ed to the stationary part 32 iu any desire position.

The stationary part 32 is some portion ol the traine of a machine disposed over a re ciprocating table on which is mounted the article to be acted upon by the projecting bristles 22 of the various units 16.

One use ot' the brush is in connection with a paper coating machine `in which coloring matter is applied to one A,face ot a roll of paper by rotary brushes, the paper then passing overa bed and under` a `plurality of brushes ortho type herein shown and described, i these brushes being reciprocated over the coated tace oi' the paper in dilierent directions and spreading the coloring matter evenly over the. entire liace.

As the machine itself iiornis no part ofthe present invention, it is deemed unnecessary to illustrate the same in detail.

lVhile in Fin. l the corrugations of the various units 1G are shown alined, il desired these corrugations may be staggered, as shown in Fig. l), so that the bristles in one `unit will be opposite the spaces between the groupsofbristles in the next unit.

Owing to the projections 17 extending into the grooves ot the channel bars la, there can be no vertical movement olf the various units, and owing to the clamping screw 2S, all movement of these units endwise of the frame 10, 12 is elfectually prevented.

At the same ti1ne,when it is desired to re place the worn bristle-supporting units lll by others, thiscan be readily accomplished in an obvious manner. y

This makes a very simple iorm of brush for heuvymachines providing means whereby it may be securely clamped in position `to a stationarv part ot the trame.

It isbelieved that the operation and many advantages of the invention will be understood without further description.

Having thus described my invention, l claim- 1. A brush consisting ol a frame having parallel side members with oppositely disposed grooves therein, a plurality of bristlesupporting units the ends ot Whit-hare disposed in said grooves, a member pivoted to one end ot said trarne,` and au adjusting screw carried by said pivoted member and adapted to clamp said units together'. l`
